A home's HVAC system is often underappreciated. Depending on where you live, the system could be working 24 hours a day for almost half the year. HVAC stands for Heating, Ventilation, and Air Conditioning and the system is responsible for keeping your home climate controlled throughout the year.

When it comes to your HVAC system having issues, it is better to take care of problems sooner rather than later. What starts out as a minor issue could turn into a catastrophe if it isn't addressed as quickly as possible. The last thing you want is to have to undertake the task and the cost of a complete replacement of an HVAC system.

Four Signs You Need To Have Your HVAC Serviced 

 1. Noise - Are you noticing your HVAC system making a peculiar noise when it turns on or while it is running? This is usually a sign maintenance is needed, especially is the noise sounds like grinding or rattling. This generally means there is a problem with the air conditioner or the furnace units themselves. 

2. Thermostat - Are you not noticing a difference in temperature when you adjust the thermostat? This is a clear sign your thermostat is having issues which either requires maintenance or a complete replacement. 

 3. Yellow - Check your furnace flame from time to time. If you are noticing a yellow flame instead of a blue flame, there is an issue. This is a sign the system is producing carbon monoxide. This can be extremely dangerous and even fatal. 

 4. Check Your Bill - Are you noticing a drastic increase in the total of your energy bills at the end of the month? This is a clear-cut sign that your system is being overworked. An overworked system already has existing issues that are only going to get worse if neglected.
